Munich-based chemical company WACKER is expanding its product range with a new liquid silicone rubber for the production of automotive gaskets. Molded parts made from the new silicone are resistant to heat and coolant and exhibit low compression set even under permanent stress. Car radiators and cooling-system components can thus be reliably sealed. ELASTOSIL® RT 728, as the new silicone grade is called, can be injection molded or mechanically dispensed straight onto the part to be sealed.
